“I think Brook can box a very clever fight and use straight shots to get the victory. He needs to watch Sugar Ray Leonard against Marvin Hagler because that fight is the key to him winning this one. GGG is a great fighter but he hasn’t got the ability that Kell has – Brook is the far superior boxer.

“Kell can be the biggest superstar in boxing and the best British fighter ever if he can overcome Golovkin. I’m willing him on to win so much and he just needs to realise that he has the ability and skill to get the job done.

“He needs to be ready for 12 rounds of relentless pressure and hard punches and be able to take and absorb it. More importantly, he needs to avoid a lot of it and slow down the fight with his brilliant jab.”
